Douglas County PUD Utility Pole Replacement

 

NGA was hired by Douglas County PUD to gather subsurface information for the installation of large monopoles for high tension transmission cables.

The job site required a drilling contractor specializing in difficult access drilling (Salisbury & Associates) to complete a 50 foot deep, diamond-core boring above the US Hwy 97 and the Columbia River.

The original, 70 year old power poles were said to have been drug up the hill by a team of mules!
